My head unit stopped playing CD's, but radio still works.. Help

As I started to drive off to school today, I put a CD in my head unit and it seemed like it tried to read the CD but then it spit it out. The radio still worked fine. None of my CD's, burned and bought ones didn't work. I reset the CD player but still didn't work. What can I do? My HU is a cheap Kenwood that is probably 3-4 years old.

yep sounds like the laser is shot. One thing you might try is using a can of air to clean it out. You may get lucky and get it to work. Just stick the little straw in the slot and give it a couple of blast of air. If it is out of waranty anyway you could open it up and clean the laser with a Q-tip and some alcohol. It may not help but it is worth a shot.
